4-beat is a kind of repeated beat, and its periodicity is: strong beat, weak beat, sub-strong beat and weak beat.
On the first beat, keep your hands at a proper distance and clap your hands downward. The reflex action will bounce naturally with the clapping action, so be careful not to lean out too much. The reflex action of the first beat? In fact, it has become a preparatory action to command the second beat.
The second beat is weak, and the command action is on the inner side of the first beat, so the amplitude of the stroke action is reduced accordingly, and the hands cannot cross when reflecting, at most, the palms overlap slightly.
The third beat is a strong beat, the flapping action goes to the outside (slightly downward), and the reflection action bounces up.
The fourth beat is a weak beat. As the reflection of the third beat naturally falls back, the fourth beat goes down and the reflection bounces up from the inside.
